2021 Kia Forte GT-Line
The fact that every time you move that coil you get a new code for the cylinder it's in, should tell you the problem.
Every time he moves that coil the misfire moves to the new cylinder and he didn't clear the codes between moving.. coil is badIf you have every coil back in it's original position, clear the codes and then start the car. If the P0302 comes back, replace the coil on #2. Clear the code and then start the car and see if P0302 come back up. I'm willing to bet it doesn't. It's pretty strange that #2 on your car has gone bad and #2 on my car did too. Coincidence?? Maybe not.
Check coil, these cars have a known issue with coils failing or the RFI spring inside of it. It could just be a bad coil as well.On way home check engine light came on. Got home and hooked up code reader and got the P0302. Just replaced spark plugs a couple weeks ago. Also a new AEM air filter installed also.When giving it gas it was sluggish at times. But when I took foot off gas pedal check engine light went off. Foot back on and check engine light back on. Car has 104,777 miles on it. Would replacing just coil pack fix issue.
